In this paper, we explore the application of a fast phase unwrapping method in digital holographic interferometry for deformation analysis. In the proposed approach, we formulate the phase unwrapping equation using Poisson’s equation and solve it using graphics processing unit computing. We demonstrate the method’s ability to handle noisy signal data in a computationally efficient manner using numerical simulations. We also present the experimental results to show the method’s practical utility in digital holographic interferometry. © Anita Publications. All rights reserved.
